USA Today interviewed Dr. Timothy Brewer, UCLA Fielding School of Public Health professor of epidemiology, about research that found children’s birthday parties may be partly to blame for increased coronavirus transmission rates
Kids' birthday parties may be partly to blame for increased coronavirus transmission rates, a new study shows.
The study, published in JAMA Internal Medicine on Monday, gathered private health insurance data from 2.9 million U.S. households from Jan. 1 to Nov. 8, 2020. In counties with high rates of transmission, households were 31% more likely to test positive for the virus that causes COVID-19 within two weeks after someone had a birthday.
In households where a child’s birthday occurred, there were 15.8 more positive coronavirus tests per 10,000 people than in households that didn’t. When adults had a birthday, there were just 5.8 more positive tests in the following two weeks.
